Answer:
The rate of change is 1 mile per hour per month
Step-by-step explanation:
We are given
initial speed = 3 mph
final speed =6 mph
total number of months =3
now, we can use rate of change formula
we know that
rate of change = ( final speed - initial speed)/(total number of months)
now, we can plug values
and we get
Rate of change is
mph per month
=1 mph per month
Point slope form is :
8+12 = m(9-4)
8+12= 9m -4m
20= 5m
20/5= 5m/5
m= 4
Slope form
8= 4(9) +b
8= 36+b
-28=b
Y= 4x -28
8.5 or 8½
Arranged numbers in ascending order
2, 6, 8, 8, 9, 10, 12, 14
Median = middle number i. e 8 and 9
Therefore median = 8 + 9 divided by 2
= 17 divided 2
= 8.5
Answers = 8.5 or 8½
third option is the correct answer....
